    Counting shapes

    I have couple of text files with some drawn shapes made of . and +
    for example:
    ........................................
    .........+++.........................
    .........+++.......+++++......
    .........+++........+++++.....
    .........+++.......+++++......
    ....................++++...........
    ....+++++.........+++.........
    ...+++.+++.......................
    ...+++.+++...........++.......
    ...+++.+++...........++.......
    ....+++++........................
    .......................................
    I am reading this text file info an 2D array.
    Looking at the example I see 4 shapes made of +

    But how how can I count them inside my program?
    Can you guys give me an idea how to construct a counter of how many shapes (made of +) are present.

    Look for a +. Add one to shape_count, and turn every + connected to that + into a . Repeat until finished.
